    sgiioc4: fix messages · 9b5a18e1
    Sergei Shtylylov 提交于
    Fix several issues with the log messages printed by ide_dma_sgiioc4() and
    sgiioc4_ide_setup_pci_device():
    
    - IOC4 registers are memory-mapped but the "BM-DMA at" format corresponds to
      I/O  mapped registers;
    
    - "%p" format specifiers and type casts used to print non-pointer values;
    
    - using KERN_INFO log level for the error message;
    
    - 'hwif->name' printed as drive's name.
    
    While at it, also:
    
    - return more fitting -EBUSY if request_mem_region() fails;
    
    - make the error message style consistent;
    
    - fix indentation, put the printk() facility and message on the same line;
    
    - use comparisions with NULL instead of ! operator..
